What effect does the Earth spinning on its axis have on winds and currents?

• Global winds will move along a straight path and will have no effect on ocean currents.

• Global winds will move along a curved path and therefore cause ocean currents to curve.

• The moon's gravitational pull on the Earth is increased, causing water to move up the coast.

• The density of the water is increased causing the water to sink, forming deep ocean currents.

How are convection currents produced in the air?

• Wind causes convection currents by stirring up the air.

• Warm air is less dense, so it rises. Cold air moves in to take its place.

• Cold air is less dense, so it rises. As the cold air rises, warm air descends.

• Big weather events like hurricanes and tornadoes cause convection currents.
